Given numbers are 162, 290, 817, 243

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(162, 290) = 23490

GCD(162, 290) = ( 162 x 290 ) / 23490

= 162 / 290

= 162

Step2:

LCM(2, 817) = 1634

GCD(2, 817) = ( 2 x 817 ) / 1634

= 2 / 817

= 2

Step3:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

So, Greatest Common Divisor of 162, 290, 817, 243 is 1
